Specification of Letters Patent No. 6,055,v dated January 23, 1849.

To all whom t may concern f vented a new and useful machine for einAbossing, folding, and gumming paper for envelops for letters, papers,cards, packages, or any other like use, which we denominate The envelopfolder, glimmer, and embosser; and we do hereby declare the following tobe a full and exact description of ment, and operation.

The nature of our invention consists in the combining and arranging in atable orl frame certain levers or treadles, having upright sliding barsconnected thereto for stamping or creasing the paper for envelops, andgumming the edges o-f the same, with a folder frame andfolders-attached, in such a manner as when the treadles are operatedupon by the attendant of the machine, the paper is gummed and foldedinto envelops at one operation. But to describe our invention moreparticularly, and the combination of the several parts of the same, wewill refer to the accompanying drawings.

Fig. 1, is a front view or elevation of the machine having a portion ofthe table removed so as to exhibit t-he folders more fully. Fig. 2, is aside elevation, and as in Fig. 1, has apart of the table remo-ved toshow the folders more fully, and which are raised as in the act offolding the paper. Fig. 3, represents a top view of the machine. Fig. 4,a front view of the folder frame, and apparatus as detached from thetable and stamper. Fig. 5, a view of the top of the folder frame. Figs.6 and 7 representations of the folder square and wings or leavesattached thereto by hinges for folding the paper. Fig. 8, is thestamper. Figs. 9 and 10 are views .of the stamper bar, and lever forworking the gumming apparatus, and Fig. 1l, a representation of thegumming apparatus and connecting rod and section of the lever forworking it.

In each of'the severalV drawings the same letters refer to the sameparts wherever they occur.

Letters A A A, &c., represent the frame of the machine. Letters B, B, B,&c., in Figs. 1, 2, 3, and 9 are several views of the stamper rod orlever.A This stamperV rod o1' lever may be made of iron or vany othersuitable material. At its lower end is a connecting rod keying to it,and to a treadle, (see let-ters 0,0, &c.), for thepurpose of yworkingthe stamper bar up and down, toy

crease'or stamp the paper, by means of the stamper or creaser (D,'D,&c., Figs. 1, 2 andV 8,) attached to the bent end ofthe stamper bar, bythe binding screws E, E,]1l, 5c. This stamper or creaser D, is made inthe' form of an oblong square, (or any other .form suit-able forenvelops), and has its edges r.slightly bent downward, so that, whenlbrought down ongthe middle piece of the folder L', it creases or breaksthe paper, as the folder leaves L2, &c., are being raised to `l gfold'over or down its edges. of the stamping bar is a notch B2 see Figs.

On the back 2 and 9.` This notch, when the stamper bar is drawn down bythe treadle C, catches into a corresponding notch cut in the end of thegumming apparatus lever (F, F, &c., Figs. 2, 3 and 9) and draws it downuntil t-he gummers have gummed the edges of the paper, (when it slipsfrom olf the notch)- and is drawn up again bythe reaction. of the'spiral spring F2, while the stamper is creasing the paper preparatory-toits being folded. Letters F, F, &c., Figs. 2, 3, and 10,-10, arerepresentationsof the gummingl lever or spring. From out the end'of thelever is cut a square notch corresponding to the width of thestamper-bar B, and fitting into the notch B2, on the back of it, and

to take hold of the lower end of the spiral spring F2 for the purpose ofkdrawing back the lever, and a spiral spring F2y on itsendf and againstthe upper girt piece of the frame,v for the purpose yof keeping theVnotched end of the lever always in Contact with the back of the stamperbar, when drawn down by ythe notch B2, and back' again by the spring F2after slipping from the notch B2 and the edges of the envelops have beengummed. I p

Letters G, G, &c., Figs. 1, 2, 3 and' 11, are representations of thestem of the` gumming apparatus, and G2, &c. the rod connecting its lowerend to the lever F, so as to admit of its vibrating as thev lever F,- isdrawn down, and springing back on slipping from the notch, on thesta-mper bar.. Upon the velops; Letters J, J, &c., Figs. l, 2, 8, and-11, are the, gumming apparatus arms, on the outer ends of which Aarebrushes or sponges, for gumming theedges of the en-` velop paper, whenbrought into contact with it, andthe charging or feed sponges K and K,(Fig. 3,) l-directly underneath them on the face of the table, and atthe edges of the folders. Letters L, L, and L2, &c., Figs. 1,i 2, 3, 4,and 6, are representations of the folders let into the topu of thetable, so as to be level with it, and by means of the bolts or screwsL4, L4, &c., on the under side of it, held down to the top of the table.On the. four sides of the folder square, L', are' wings or leaves L2,L2, Sac., jointed to the middle piece L so that, when the stamper D, hasgiven an impression or creasing to the envelop paper and before beinglifted from' it, the leaves (L2, &c.,) may begin to fold or break theedges of the paper up tothe required shape, and while the stamper D isbeing withdrawn, completes the folding of them over, and sealing them bypressing together their gummed edges. These folder wings (L2, &c.) haveon their lower sides a right angled lever or leg, having a fulcrum at apoint where they hinge to the middle piece (L), and braced or 'stiiienedby a shoulder piece as represented in Fig. 7.' To the lower legs of thefolder Wings are attached, by oints the upper ends of the foldingapparatus rods` M, M, &c., Figs. 1, 2, 4, and 7 These rods are connectedat their lower ends to the top piece of the folder apparatus frame N, N,&c., Figs. l, 2, 4 and 5, and extend upward with a gradual curve, untilwithin an inch and a half of their upper ends, when ,they are bent atright angles, and connected by a hinge joint to the lower leg of thefolder wings for the purpose of working them in the semi-circular motionrequired for `folding the paper. n

Letters N, N, &c., Figs. l, 2, 4, and 5, are representations of the toppiece of the folding apparatus frame. In Fig. 5, it shows the two slotscut out of it, for connecting the ends of the side folding rods to thespring underneath, (see l?, P, &c., Figs. 1 and 4) and two holes, (oneback and front), for the ends of the front'and back folding rod levers,M and M, to be inserted and attached thereto. These rods or levers M, M,&c., are bent outward, and connected to the top piece N; the two sideones through slots to the 'ing it.

The operation of these several parts is that when the treadleA C, andstamper bar B are brought down, the notch B2, on the back of the bar,catches into the end of the lever F', which it bends down, and also,thegumming` apparatus (Gr-G2 and H, I, J,) until the gummers J, have gummedthe edges of the paper, when the end of the lever F, slips oil" thenotch B2, and is` drawn up again by the spiral spring F2, attached toits upper side and the lower side of the table. While this is beingdone, the stamper D, is brought down through the center ofthefolderframe, e

down on the middle piece of the folders` L',

and the paper, to crease or stamp` it, and held there, (that is on thepaper) until the operator raises the treadle W, and folding apparatusattached thereto, so as to elevate the leaves L2, to a point nearly atright angles to the plate LI', for the purpose of completed and theenevelop may be removed..`
